Description
This panel measures IgE (Immunoglobulin E) antibodies to 50 common airborne allergens. It helps identify immediate-type allergic reactions (Type I hypersensitivity), which are typically associated with conditions such as:
- Allergic rhinitis (hay fever)
- Asthma
- Atopic dermatitis
- Allergic conjunctivitis
It also includes Total IgE, which gives a general indication of allergic or atopic tendency.

Test Details:
- Includes: Total IgE + Specific IgE for 50 airborne allergens
- Sample Type: Blood
- Collection Time: Monday–Friday before 4:00 PM
- Fasting: Not required
- Turnaround: Up to 21 business days (excluding shipping)
Clinical Usefulness:
- Positive IgE results suggest immediate-type hypersensitivity—helpful for targeted allergy avoidance, immunotherapy (allergy shots), or medications.
- Total IgE helps gauge overall allergic predisposition but must be interpreted alongside clinical symptoms.
Key Differences: IgE vs. IgG Panels
1. Type of Immune Response
- IgE Panel: Measures immediate allergic reactions (Type I hypersensitivity)
- IgG Panel: Measures delayed immune responses (Type III or IV hypersensitivity, often called "sensitivities")
2. Clinical Use
- IgE: Commonly used in diagnosing allergies (e.g., hay fever, asthma, eczema)
- IgG: Often used in functional or integrative medicine to evaluate potential food/environmental sensitivities (controversial in conventional medicine)
3. Symptom Onset
- IgE: Symptoms occur within minutes to a few hours after exposure
- IgG: Symptoms may occur several hours to days later
4. Interpretation
- IgE: High levels indicate a true allergic reaction
- IgG: Presence of antibodies may indicate exposure or tolerance, not necessarily an adverse reaction
5. Medical Acceptance
- IgE: Widely accepted and used in mainstream medicine
- IgG: Limited acceptance in conventional medicine; more research is ongoing
